Mountain, Pasadena, Calif. Filed Feb. 27, 1962, Ser. No. 176,007 Claims. (Cl. 248-63) This invention relates to power conductor suspension assemblies and more particularly to an improved heavyduty type featuring ruggedness coupled with high strength and lightweight as well as an improved cable clamping jaw. More particularly, the invention relates to a bundling type clamping assembly by means of which a plurality of high tension power conductors are supported by a common metallic assembly pivotally supported at the lower end of the insulator assembly, thereby increasing the effectiveness of the power line to carry high Volta es without risk of arc or fiashover and making it feasible to eliminate control shields heretofore considered necessary under heavy loading conditions.

Recent studies of limitations on the load carrying ability of power have established definite advantages attending the division of the load between two or more conductors in spaced-apart relation and held in rigidly spaced relation by a common clamping assembly known as a bundling clamp. Among the advantages of this practice is the fact that a given insulator assembly to operate safely at appreciably higher voltages without accelerated corrosion damage to insulators and the production of localized corona so conducive to the generation of radio interference voltages. A major reason for the improved operating characteristics is the fact that the separation of the power cable into several cables reduces the field intensity over a sizable region surrounding the conductors. This enables the conductors themselves to perform part of the control functions of the commonly used control shields.

The present invention provides a relatively simple, high efiiciency bundling suspension assembly so designed as to support two or more conductors in vertically spaced alignment with the axis of a suspension insulator.

To this end, the assembly comprises an enlongated main body having a clevis connection with the lower end of the insulator and having an eyelet at its lower end for supporting an anti-sway weight or its equivalent. Pivot-ally connected to the main body on vertically-spaced horizontal axes are separate keeper jaws shaped complementally to semicylindrical conductor seating saddles formed integral with the main body of the clamp and projecting from the oppois-te sides thereof. Each of the jaws preferably includes a pair of elliptically shaped clamping screw openings having novel means for holding these screws captive therein. The threaded ends of the screws mate with cooperating th eaded bores provided in the main body to the end that the conductors can be rigidly and firmly clamped in place substantially throughout their circumference. The smaller diameter nonthreaded shank portion of the screws cooperate with restrictors at the outer ends of the supporting openings for these screws. These restrictors have shallow threads engageable with the threaded ends of the screws in a manner requiring skilled manipulation before permitting assembly and disassembly of the screws with respect to the jaws and operating normally to hold the screws captively assembled to the paws. This safeguard makes it feasible to open and reclose the clamping jaws through long-handled wrenches manipulated from a remote point such as the ground without risk of the screws becoming unintentionally detached from the jaws.

A further feature and safeguard is that the length of the mounting openings for the screws is as great and preferably greater than the length of the threaded portion of the screws. In consequence assurance is provided that ice the screws will become disengaged from the threaded bores in the main body of the clamp before the shank end of the screws can engage in the threads in the restrictor holding the screws captive with the jaw. Other features and advantages of the assembly will be pointed out in detail below.

Accordingly, it is a primary object of the present invention to provide an improved cable suspension assembly useful in connecting high tension power conductors to transmission line insulators.

Another object of the invention is the provision of an improved cable suspension assembly having a cable seating saddle together with a clamping jaw therefor featuring threaded fastener means for clamping the jaw to the cable and including simple, highly effective means for holding the fastener means loosely but captively assembled to the clamping jaw.

Another object of the invention is the provision of an improved, rugged bundling-type suspension clamp by which a plurality of conductors can be supported in spaced-apart parallel relation below an insulator.

Another object of the invention is the provision of a bundling cable suspension assembly having a main body pivotally supporting a plurality of clamping jaws for the separate components of a single leg of a power transmit ting cable.

These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawings to which they relate.

Referring now to the drawings in which a preferred embodiment of the invention is illustrated.

FIGURE 2 is a transverse sectional view taken along the broken line 2-2 on FIGURE 2;

FIGURE 3 is a fragmentary transverse sectional view through the upper end of the assembly and taken along line 33 on FIGURE 2;

FIGURE 4 is a view taken generally along line 4-4 on FIGURE 1 but showing the upper clamping jaw in open position and the power cable removed; and

FIGURE 5 is a sectional view on an enlarged scale taken along line 55 on FIGURE 4 showing details of the restrictor for the clamping screws and effective to hold these screws captively assembled to the clamping jaw unless properly maneuvered for disassembly therefrom.

Referring more particularly to FIGURES 1 and 2, there is shown a preferred embodiment of a bundling clamp designated generally 15 and incorporating the invention features. The three principal parts of this assembly include an elongated main body 11 and a pair of identical hinging keeper jaws 12, 13 held assembled to the main body by separate hinge pins 14, 14.

Main body ll comprises a unitary casting of high strength lightweight metal, such as aluminum alloy or the like, and is provided at its upper end with a clevis 16 held pivotally assembled to a high strength tang 17 depending from the lower end of a high tension, multiple component insulator train 20 of conventional construction. A clevis pin 21 extends through aligned openings of the clevis and tang and is secured in place as by a cotter pin 22. Integral with the lower end of main body 11 and in vertical alignment with insulator tang 17 is an eyelet loop 25 useful in supporting an anti-sway device for the power line, as, for example, a weight. As is well known, these weights tend to counteract the influence of high winds acting from the side of the cable and tending to swing the conductors.

Desirably, main body 11 of the suspension assembly is shaped for maximum strength using a minimum amount and weight of material. From a consideration of FIG- URES 1, 2 and 4, it will be recognized that the main body portion is of H-shape in cross section, there being a pair of parallel side flanges 28, 23 connected together by a centrally disposed integral web 29. This vertical web lies substantially in a plane common to the longitudinal axes of both conductors 30, 30, side flanges 2%, 28 lying normal to web 29 and to either side of a vertical medial plane through the axis of clevis 16, as is best shown in FIG- URE 1.

Referring now to FIGURES 3 and 4, it is pointed out that the main body 11 of the assembly includes substantially identical conductor seating or saddle members 31, 32. These saddle members comprise an elongated, horizontally disposed, semicircular support preferably contoured generally as shown in the drawings and disposed to embrace one lateral side of the respective conductors 3t), 30. The open faces of these saddle members lie substantially in a vertical plane closely adjacent the longitudinal axis of the assembly and open outwardly toward the respective clamping jaws 12, 13. The opposite lower ends of members 31, 32 preferably curve downwardly and outwardly away from one another, as indicated at 33, and have rounded and slightly thickened lips for greater strength. These rounded surfaces and lips avoid risk of injury to the cables while being serviced and as sembled within assembly 10. Referring to FIGURE 3, it is pointed out that one edge area of one lip is preferably provided with an opening 35 in axial alignment with hinge pin 14 and facilitating the assembly and disassembly of this pin for reasons readily apparent from a consideration of FIGURE 3.

The identical clamping or keeper jaws 12, 13 are contoured as shown in FIGURES 1, 2 and 4. In general, these comprise horizontally elongated members of semicylindrical shape and having an inner surface the radius of which corresponds to that of the inner surface of saddle members 31, 32 and with that of the conductor to be supported. The exterior or outer side of the jaws include arcuate but radially disposed reinforcing ribs 37 having their lower ends (FIGURE 1) spaced laterally to either side of flanges 28, 28 of the main body. The lower ends of these ribs constitute lugs forming part of the hinge connections between the jaws and the main body. Cooperating with these lugs for this purpose is a pair of shorter lugs 38 positioned against the interior side walls of flanges 28. These two pairs of lugs as well as the intervening portion of main body flanges 28 are provided with aligned openings 39 having a rotating fit with hinge pin 14 and preferably held in assembled position by a single cotter pin 40 extending through a transverse opening in the center of the pin (FIGURE 3).

As will be best understood by reference to FIGURE 4, opening movement of keeper jaws 12, 13 is limited by a stop 42 projecting from the outer side of the jaws and positioned to engage the adjacent edge of flange 28 as the opening movement of the jaw reaches the upwardly inclined position shown in FIGURE 4. While so rigidly supported, the semicircular interior of the jaw lies in a position to cradle and hold a conductor captive until the jaw is reclosed. As will be apparent, the upward pivotal movement of the jaw serves to cam the conductor upwardly and inwardly toward seating engagement with the surfaces of saddle members 31. Contrariwise, opening the jaw from its closed clamping position allows a conductor present in the assembly to gravitate outwardly into the open jaw where it is more readily lifted away from the suspension assembly. Desirably, the arcuate movement of the jaws between their fully open and closed positions is somewhat less than 90 degrees. However, as will be appreciated, this path of movement may be increased or decreased to suit the needs of a particular application and the particular disposition of the open face of the saddle members.

The means for clamping the jaws snugly against movement lengthwise of the cable will now be described. For this purpose, each of jaws I2, 13 is provided with a pair of bosses 45 integral with its upper lateral edge and spaced clojsely to the outer sides of main body flanges 28, 28. Extending centrally through these bosses are noncircular and preferably elliptical bores 46 loosely receiving the shanks of threaded clamping fasteners for the jaws, such as cap screws 47. The threaded ends 4% of these screws are mateable with the threaded bores of bosses 49 integral with main body 11. The longer axis of the elliptically shaped passages 46 lies in a vertical plane whereas the minor axis extends generally horizontally. This minor diameter i sufliciently greater than the diameter of threaded end 48 as to permit free and unrestricted movement of the cap screws within passages 46.

Referring more particularly to FIGURE 5, it is pointed out that the inlet or outer end of passages 46 is provided with restrictor means such as inwardly projecting, radially shallow narrow lips 51, 51 having their adjacent inner edges spaced closer together than the crest diameter of the threaded end 48 of the screws. It is further noted that the spacing between the inner edges of lips 51 is slightly greater than the reduced diameter of the nonthreaded shank 52 of the screws. Accordingly, it will be recognized that these shanks are free to move freely axially of opening 46 past restrictor lips 51 until the lips engage the rearrnost ends of threads 48. Provision for the as sembly and disassembly of the screws past lips 51 is had by cutting a shallow thread in these surfaces thereby permitting the screws to be threaded past these restrictors. This is done most simply by using the screw itself to cut the requisite shallow threads in the restrictors. Once this i accomplished, the screw is free lengthwise of passages 46 without interference from restrictor lips 51.

Additionally, it is pointed out that the axial length of threads 48 is no greater than the unrestricted length of passages 46 and preferably slightly shorter. This assures that the screw threads will be fully disengaged from main body bosses 49 before the rear ends of threads 48 can possibly engage the shallow threads in restrictor lips 51. Also, it is desirable that the threads in lips 51 be formed near the upper ends of these lips or close to the upper half portion of passages 46. This arrangement requires that the operator deliberately lift the screw into the upper portion of these passages in order to engage threads 4S with the threads of the restrictor thereby providing further assurance against accidental displacement and loss of the screws from the clamping jaws.

It is also pointed out that the substantially continuous support and rigid clamping of the conductor about its entire circumference and particularly from its sides, as distinguished from its upper and lower sides as commonly done prior to this invention, has important advantages. For example, cross winds or other disturbances may cause lateral oscillation of the conductors between towers. If the sides of the conductors are not tightly clamped and supported at their sides, the wires in these sides are alternately slackened and tensioned and this leads to rupture and failure of these wires. Soon thereafter the conductor itself fail at the clamping assembly. Such failure is positively safeguarded against in the present clamping assembly because of the rigid supporting action along the sides as well as about the entire conductor for reasons made clear by FIGURE 2.

While the particular power cable suspensionassembly herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the details of construction or design herein shown other than as defined in the appended claims.
